Question

when two liquids x and y are mixed the solution becomes warmer. when two solutions a and z are mixed the solution become cooler. which of the following solutions will exhibit negative deviation from raoult's law

Answer 1

Answer:

As the heat is evolved, the enthalpy change is negative. It must be exothermic and also shows negative deviation from raoult's law.

Reason for negative deviation: The intermolecular forces between A-A and B-B are weaker than those between A-B. So, when u mix these kind of solutions, heat will be released and also it leads to decrease in vapour pressure.
